+# Adds a library target for a Quassel module.
+#
+# quassel_add_module(Module [STATIC] [EXPORT])
+#
+# The function expects the (CamelCased) module name as a parameter, and derives various
+# strings from it. For example, quassel_add_module(Client) produces
+# - a library target named quassel_client with output name (lib)quassel-client(.so)
+# - an alias target named Quassel::Client in global scope
+#
+# If the optional argument STATIC is given, a static library is built; otherwise, on
+# platforms other than Windows, a shared library is created. For shared libraries, also
+# an install rule is added.
+#
+# To generate an export header for the library, specify EXPORT. The header will be named
+# ${module}-export.h (where ${module} is the lower-case name of the module).
+#
+# The function exports the TARGET variable which can be used in the current scope
+# for setting source files, properties, link dependencies and so on.
+# To refer to the target outside of the current scope, e.g. for linking, use
+# the alias name.
